KOCHER, or BOONTON, NEW JERSEY, AssieNoE TOAUTO RESEARCH CORPORATION, A CORPORATION or DELAWARE LIQUID DISTRIBUTING INSTALLATION AND THE ELEMENTS THEREOF f Original application filed July 18, 1925, Serial No. 44,498. Divided and this application filed October-'31,

1930. Serial My present invention relates primarily to liquid feeding and distributing fittings particularly to junction fittings and flow controlling instrumentalities and while of more general application, has a preferred use in lubricating systems and a specific application to automobile chassis lubrication.

It is an object of the invention to provide a simple, inexpensive and durable junction fitting to which pipe terminals may be controlling instrumentallties.

Another object is to provide a fitting of the above type which lends itself to ready association with the bearing structure which completely houses and protects the flow control instrumentality therein and yet affords ready access for replacement of such instrumentality when desired.

Another object is to provide a fitting of theabove type, which may be associated directly to a bearing without requiring any large bored and/or tapped opening adjacent the bearing surfaces.

Another object is to provide a lubricating installation, the multi-junction elements of which are conveniently installed with definite assurance that their pipe connecting. arms or nipples shall extend in proper directions when said junction element is rigidly aflixed with respect to the bearings or to the carrying structure.

Other objects are in part obvious and in part ointed-out hereinafter.

A eature of the present invention reside in providing a junction fitting affording communication between one or more conduits and/or a bearing structure, and having a cavity completely enclosing a flow controlling unit determining the feed to a bear- 1 ing and removably fitted into said cavity, said junction fitting'being adapted to be mounted directly to the fixed element of the bearing.

In a preferred embodiment of the invention,'the junction fitting is provided with a tapped cavity or socket to. receive a longi- No. 492,507. I I

tudinal threaded cartridge-like fiow' fcontrolling instrumentality, said fitting-being also desirably provided with a suitable number of pipe connecting nipples and with mounting flanges. .In said embodimentthe flow control instrumentality ma have a central longitudinal bore. substantially filled by a restriction pin, both pin and-bore being of accurately predetermined almost e ual diameters to impose a high resistance to fiow t-herethrough. A valve may also be preferably associated with each flow controlling instrumentality and, if desired, normally springseated to prevent flow except under pressure.

In the accompanying drawing in which there is shown one embodiment of several features of the present invention Fig. 1 is an elevation of one form of junction fitting, and V Fig. Qis a'view in longitudinal section taken alongthe line 22 of Fig. 1.

In Figs. 1 and 2 the junction fittingnot only provides for direct distribution of Inbricant in two or more paths, but also affords an outlet for emission of lubricant in a controlled manner to an adjacent lubricated element. This embodiment includes a domeshaped casting having a flange 71 extending at right angles from the open end thereof, the desired number of nipples 72 integrally cast with the dome-shaped member protruding generally radially from near the closed end thereof. In this instance, three such nipples 72 72 and 73 are shown, 72 having an angle bend 74, so that its threaded end may extend generally parallel to the major axis of the flange71 for convenient application of a pipe terminal after the fitting has been applied. Any one of the nipples may serve as the inlet and the other two as theoutlets for lubricant Within the dome 70, I provide a flow controlling cartridge, which maybe generally similar to that shown in the T-fitting, disclosed in my copendingapplication Serial No. 22,104, filed April 10, 1925. I have here shown a specifically diflt'erent embodiment comprising a cartridge 75 having a pipe thread 7 6 intermediate its ends for coactionf limiting sense.

with the correspondingly tapped portion 77 on the side of the dome-like cavity, said cartridge being of reduced diameter at the innermost part 78 to afford a substantial clearance with respect to the inner wall of the dome. I

y The cartridge is provided with a socket at its innermost end within which is di posed a strainer plug 81 of felt backed preferably by a disk or cup 82 of fine wire mesh pressed against a shoulder 83 therein and held in place by a perforated cup 84 friction-fitted thereinto. The main part of the length of the cartridge is preferably provided with a longitudinal bore within which fits a metal pin 85'also of accurately predetermin'ed diameter, affording minute clearance with respect'to the bore. At the outer end, there is provided a relief valve 86 which may be pressed by a coil spring 87 against a seat 88adjacent the end of the pin 85, said spring being held in place by a perforated friction-fitted cap 89. The outer end of the cartridge75 is preferably provided with a fillister slot 90 which may be engaged by a screw driver for mounting the cartridge in the dome-shaped fitting.

I By. the expression flow controlling and obstructing instrumentality as utilized in the accompanying claims, is meant a de vice, which; may take the form, of a pipe fitting, including a valve, a restriction and/ or a strainer} Under certainconditions the preferred form of flow controlling and ob structing device shown enclosed inthe socket of the junction device in F ig. 2 may be modified so as to omit one or more of the flow controlling and obstructing elements shown, namely, the restriction, the strainer and/or the valve or replace them by other similarly functioning elements.
